VP20 / VP20BV Mid Series Modular Venturi Vacuum Generator

VP20 Series Modular Venturi Vacuum Generators
VP20 Mid Series air-powered venturi vacuum generators are the most commonly used generators for pick & place applications due to their ease of mounting and the variety of options and accessories available. Vaccon Mid Series vacuum generators provide maximum design versatility: designers specify only the features necessary for their specific application.
VP20BV models offer a 2-way integrated valve. Vaccon’s interchangeable venturi cartridge system enhances manufacturing flexibility, enabling designers to choose the vacuum level, vacuum flow, evacuation speed and air consumption based on any one of 11 venturi cartridges.
